what would you do please answer

So I have a few questions. Hopefully someone will be able to answer me. I have had asthma all of my life. I was on allergy shots until I was 19 and I moved out of state for college and the nearest place I could get them was 2 hours away. Anyways, thats not what I am asking. I grew up in Arizona, and the weather is really great for my asthma, but I moved to Missouri for college, and every summer here it is like a make or break for me for my asthma. 2 years ago me and my husband just had to get up and leave because I couldn't breathe here in Missouri and I was not getting any help at the hospital, they were just loading me up on prednisone and it was driving me crazy. Well, I guess it was the weather because when I got to Arizona I was fine. Well again this summer in May, it literally felt like a elephant was sitting on my chest, but my peak flow which is normally 540 was around 510-540 and so I didnt know what was going on again. I am allergic to grass and mold and of course the grass and mold was very high here in May, so again we got in the car and drove to arizona for the summer, and of course my breathing got better and the weight was taken off of my chest. Well we just got back to Missouri 2 weeks ago, and it was like the weight was put back on my chest right when we entered into oklahoma, and it comes and goes. Like yesterday I felt semi fine, but today it feels like a weight on my chest again. The mold is still high, but the grass is moderate to low. Anyways, my peak flow again is 510-540 depending on the blow. I have called doctors and hospitals and have told them my story and they say it is probably just the pollen. I do take singulair and advair every day. So, does anyone have any answers. I hate this, you know it pretty much always feels like I have pressure on my chest but my peak flow is fine, and not in danger there. So I dont know if it is asthma or what?????? I am just in a bind and dont know what to do, and just sitting here with this problem. We did go out and get an air purifier and dehumidifier for out apartment and when I go outside I wear one of those face masks for the air. Do you think I can do anything more. I have one more year in school and then we are moving back to arizona, since that is where I breathe the best. Please answer me I have run out of options.
